In lichens, these phases comprise dispersal, establishment, and growth. This thesis aimed at increasing the knowledge on epiphytic cyanolichens by studying different aspects linked to these life stages, including species colonization extinction dynamics, survival and vitality of lichen transplants, and the genetic symbiont diversity in the genus Nephroma. Paper I reveals that local colonizations, stochastic, and deterministic extinctions occur in several epiphytic macrolichens. Species habitat-tracking metapopulation dynamics could partly be explained by habitat quality and size, spatial connectivity, and possibly facilitation by photobiont sharing. Simulations of species future persistence suggest stand-level extinction risk for some infrequent sexually dispersed species, especially when assuming low tree numbers and observed tree fall rates. Forestry practices influence the natural occurrence of species, and retention of trees at logging is one measure to maintain biodiversity. However, their long-term benefit for biodiversity is still discussed. -
An Evolving Phylogenetically Based Taxonomy of Lichens and Allied Fungi
Opuscula Philolichenum, 11: 4-10. 2012. *pdf available online 3January2012 via (http://sweetgum.nybg.org/philolichenum/) An evolving phylogenetically based taxonomy of lichens and allied fungi 1 BRENDAN P. HODKINSON ABSTRACT. – A taxonomic scheme for lichens and allied fungi that synthesizes scientific knowledge from a variety of sources is presented. The system put forth here is intended both (1) to provide a skeletal outline of the lichens and allied fungi that can be used as a provisional filing and databasing scheme by lichen herbarium/data managers and (2) to announce the online presence of an official taxonomy that will define the scope of the newly formed International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF). The online version of the taxonomy presented here will continue to evolve along with our understanding of the organisms. Additionally, the subfamily Fissurinoideae Rivas Plata, Lücking and Lumbsch is elevated to the rank of family as Fissurinaceae. KEYWORDS. – higher-level taxonomy, lichen-forming fungi, lichenized fungi, phylogeny INTRODUCTION Traditionally, lichen herbaria have been arranged alphabetically, a scheme that stands in stark contrast to the phylogenetic scheme used by nearly all vascular plant herbaria. The justification typically given for this practice is that lichen taxonomy is too unstable to establish a reasonable system of classification. However, recent leaps forward in our understanding of the higher-level classification of fungi, driven primarily by the NSF-funded Assembling the Fungal Tree of Life (AFToL) project (Lutzoni et al. 2004), have caused the taxonomy of lichen-forming and allied fungi to increase significantly in stability. This is especially true within the class Lecanoromycetes, the main group of lichen-forming fungi (Miadlikowska et al. -
Lichens of Alaska's South Coast
United States Department of Agriculture Lichens of Alaska’s South Coast Forest Service R10-RG-190 Alaska Region Reprint April 2014 WHAT IS A LICHEN? Lichens are specialized fungi that “farm” algae as a food source. Unlike molds, mildews, and mushrooms that parasitize or scavenge food from other organisms, the fungus of a lichen cultivates tiny algae and / or blue-green bacteria (called cyanobacteria) within the fabric of interwoven fungal threads that form the body of the lichen (or thallus). The algae and cyanobacteria produce food for themselves and for the fungus by converting carbon dioxide and water into sugars using the sun’s energy (photosynthesis). Thus, a lichen is a combination of two or sometimes three organisms living together. Perhaps the most important contribution of the fungus is to provide a protective habitat for the algae or cyanobacteria. The green or blue-green photosynthetic layer is often visible between two white fungal layers if a piece of lichen thallus is torn off. Most lichen-forming fungi cannot exist without the photosynthetic partner because they have become dependent on them for survival. But in all cases, a fungus looks quite different in the lichenized form compared to its free-living form. HOW DO LICHENS REPRODUCE? Lichens sexually reproduce with fruiting bodies of various shapes and colors that can often look like miniature mushrooms. These are called apothecia (Fig. 1) and contain spores that germinate and Figure 1. Apothecia, fruiting grow into the fungus. Each bodies fungus must find the right photosynthetic partner in order to become a lichen. Lichens reproduce asexually in several ways. -
The Phylogeny of Plant and Animal Pathogens in the Ascomycota
Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus. -

Lichens of East Limestone Island
Lichens of East Limestone Island Stu Crawford, May 2012 Platismatia Crumpled, messy-looking foliose lichens. This is a small genus, but the Pacific Northwest is a center of diversity for this genus. Out of the six species of Platismatia in North America, five are from the Pacific Northwest, and four are found in Haida Gwaii, all of which are on Limestone Island. Platismatia glauca (Ragbag lichen) This is the most common species of Platismatia, and is the only species that is widespread. In many areas, it is the most abundant lichen. Oddly, it is not the most abundant Platismatia on Limestone Island. It has soredia or isidia along the edges of its lobes, but not on the upper surface like P. norvegica. It also isn’t wrinkled like P. norvegica or P. lacunose. Platismatia norvegica It has large ridges or wrinkles on its surface. These ridges are covered in soredia or isidia, particularly close to the edges of the lobes. In the interior, it is restricted to old growth forests. It is less fussy in coastal rainforests, and really seems to like Limestone Island, where it is the most abundant Platismatia. Platismatia lacunosa (wrinkled rag lichen) This species also has large wrinkles on its surface, like P. norvegica. However, it doesn’t have soredia or isidia on top of these ridges. Instead, it has tiny black dots along the edges of its lobes which produce spores. It is also usually whiter than P. lacunosa. It is less common on Limestone Island. Platismatia herrei (tattered rag lichen) This species looks like P. -

ABSTRACT This revision is based on a morphological, anatomical, and chemical study of 1,918 Specimens from twenty—one herbaria, as well as field work in Isle Royals National Park (Michigan), Haiti, and the Dominican Republic. The morphological and anatomical features are discussed in detail and twenty—nine original figures are included. The protuberances on the lower surface of g, resupiggfigg (L.) Ach. are corticate and, therefore, not true pseudo-eyphellae as often recorded in the literature. Eight lichen substances have been found in the genus: usnic acid, nephromin, zeorin, nephrin, and four unidentified neutral substances. These substances have taxonomic importance, although other workers in related genera have ignored them. The genus is placed in the Nephromaceae instead of the Peltigeraceae, where usually classified, because of the differences in ascus structure and development, conidial pros duction and the presence of a lower cortex in Neohroma, Seven species and two subspecies are recognized and a key for their identification is included along with a diagnosis, nomenclatural notes, and a distribution map for each species, Gyelnik's four new species and two new infraspecific taxa from North America are reduced to synonymy. -
